Scarlett Johansson has opened up about her romance with French fiance Romain Dauriac, revealing she is "deeply in love".

The Don Jon actress has rarely spoken about her relationship with the journalist, who she has been dating since November 2012.

But she has now told People that she is "very happy", adding: "He's my buddy. He's someone I can always rely on."

Scarlett, 29, and Romain, 31, got engaged last August, but the actress revealed they will take their time when it comes to planning their big day as they don't want to "rush through it".

"Being engaged is an exciting time to enjoy and to really savour," she said.

The couple are now living in Paris, where Scarlett sometimes cooks meals for her beau.

"I cook, but I'm no pro," she said. "I was making a white chicken chili and I had to let it reduce for a little while, so I was like, 'Let's go build a snowman while we wait.' I got a little carried away ... Three hours later, I was like, 'Oh no, the chili!' I went back inside and the house was covered in smoke."

Scarlett was previously married to actor Ryan Reynolds for two years until 2010.
